Vegetable washing method capable of separating and splitting impurities, and machine for implementing same

ABSTRACT

A method for cleaning fruit and vegetable ingredients is provided, in which the washing basket assembly agitates the water in the washing barrel to rotate upward to achieve the cleaning of fruit and vegetable. During the process of “cyclic cleaning in the barrel”, the drainage outlet in the center of the bottom of the washing barrel is closed to prevent the water from flowing out of the barrel cavity; when the drainage outlet in the center of the bottom of the washing barrel is opened and drained, the water body rotates to form eddy current drainage; fruits and vegetables in the washing basket alternately move centripetally and centrifugally. The number of exercises is proportional to the number of washes.

TECHNICAL FIELD OF THE INVENTION

This invention relates to a kind of washing method for fruits andvegetables and a vegetable washer which applies the washing method. Inparticular, the method and machine can separate different impuritiesfrom the fruits and vegetables to different space in the washingprocess.

BACKGROUND ART OF THE INVENTION

First, let us learn about—the kind of impurities in the unwashedvegetables: The first category, namely Group A impurities, are invisibleimpurities such as pesticides, viruses, bacteria and etc. that remain onthe surface of fruits and vegetables; The second category, namely GroupB impurities, are visible substances—attached or included and of arelative larger proportion, such as sand, grit or mud and etc.; Thethird category, namely Group C impurities, are visible substancesattached or included but of a relatively smaller proportion, such asstale leaves, weeds, hair, insect etc., which are included invegetables.

The problem that this patent will solve is how to remove the Group B andGroup C impurities.

Second, let us analyze how the process of traditional manual washing ofvegetables remove the three categories of impurities. Prepare two bowls.First, put water in the first bowl until the bowl is full, and putfruits and vegetables into the water and allow soaking for anappropriate time so that the Group A impurities would be dissolved inthe water, then put a hand into the water, grab a handful of vegetablesand constantly make the motion of turning, up and down shaking and leftand right shaking in the water so as to make the Group B impurities fallinto the water from the gap of the vegetables, and to make the Group Cimpurities detach from the gap of the vegetables (but the vegetables andimpurities still coexist in the same bucket), therefore the separationof vegetables from Group B impurities and Group C impurities arerealized, (This article will define the breaking the clamping force ofthe attachment of impurities and the loosening of impurities at thesurface of vegetables, as spin-off, which is also known as X operation),then grab one handful and repeat the above steps until all thevegetables in the bowl were being operated for one time, and at thisstage, half of the whole process of washing vegetables is completed. Atthis moment, the vegetables and the three kinds of impurities stillcoexist in the same bowl. Then, put the hand into the water severaltimes, each time take up a handful of vegetables, dipping in the watersurface continuously and moving above the water to dry, and then putthem into the second bowl, repeat until the vegetables in the first bowlare completely transferred to the second bowl while the three kinds ofimpurities and water are still in the first bowl, thus the step ofseparately placing the vegetables and the Group B and Group C impuritiesare realized (which is referred to as splitting, also known as Yoperation). At this point, the second half of the whole process ofwashing vegetables is completed.

X operation+Y operation=the complete process of washing vegetables.

Obviously, we can pour away the water and impurities in the first bowland then fill a full bowl of water and repeat (X operation +Yoperation), to conduct the second time of washing of the vegetables. Infact, washing vegetables in our daily life is also the process ofrepeating X+Y operation by changing the water many times.

Now, can we wash the vegetables if we just do X operation without Yoperation? In the above example, after the completion of X operation inthe first bowl, if the—vegetables are not move to the second bowl tocomplete Y operation which splits the vegetables and impurities, but apump is used to draw the water in the first bowl of water, then at thistime, vegetables and Group A, B, C impurities coexist in the same bowland are mixed together, then if someone ask you not to touch the dirtyvegetables with your hands but pour them into the pan directly, will youdare to eat? That is equal to cooking vegetables with weed, hair, sand,worm and various impurities.

This shows that, without Y operation, Group B and C impurities would notbe removed completely. Without Y operation, vegetables cannot be washedclean no matter how many times of X operation are repeated, strictlyspeaking, only half are washed, the vegetables are not washedcompletely.

The development history of the vegetable washer is reviewed as follows.

The earliest vegetable washer has no mechanical moving parts, now knownas static vegetable washer. The purpose is to degrade pesticide residuesin fruits and vegetables. The method is that putting through the waterand ozone in a closed container and place the fruits and vegetables inthe ozone-dissolved water for an appropriate time, using the strongoxidation of ozone 03 to cause the decomposition of pesticide residuesin fruits and vegetables on the surface to dissolve in water, and thenpoured out with the water. As the purpose is to wash off pesticideresidues impurities on the surface of vegetables, namely Group Aimpurities, and such vegetable washer still sells widely and is stillpopular.

Later, a Chinese patent whose Patent No. is 912 008 21.0 disclosesvegetable washer with a kind of mechanical movement, now called dynamicvegetable washer. Its program is that: Set the washing-basket in thewashing-bucket with closures (in the original text of this patent, thewashing-basket is named as ‘permeable inner bucket’, while thewashing-bucket is-called outer bucket. To unify the title does not causeconfusion, collectively referred to herein washing-baskets andwashing-bucket), bottom of the bucket is planar or quasi-planar bottomof the bucket has come through from the bottom surface of the shaft, theperipheral end of the bucket with a water inlet and the outlet, thechassis features a rotatable washing-basket drive electrical andelectronic control equipment, the upper surface of the washing-bucket isa waterproof panel. When use, the fruit and vegetables are placed intothe washing-basket, washing-basket is rotated by a motor driven, therebyforcing the water was flung by the centrifugal force within thewashing-basket basket and bucket gap then rose again to basket.Difficult sucked down into the basket again by centrifugal force flunggap baskets and buckets, so the cycle of flow, flow per share of eachcycle are through the slit of the basket of vegetables to form a rapidrelative motion with the surface of fruits and vegetables, producefriction to impurities and vegetable spin off to complete the Xoperation. It should be noted here that: the washing effect is due towater through friction, rather than the impact of falling water, theexisting vegetable washers as advertised in the television emphasizethat the vegetable washers provide a large amount of water fallingaction for flushing and washing vegetables, and these actions are calledspray. This is a technical bias, prejudice has of this technologyis-discussed below.

This patent scheme ingenious solve issues of vegetables Xoperation—except the flipping question of vegetables), although there isno solution to problem Y operation, but the inventor of the programthere is no basis in human vegetable washer concept, first put such aviable option, very impressive as a pioneer. More commendable is that,compared to the complex robot designed to imitate Mount manpowerprogram, this program's structure is simple and low cost. The programhas been widely used since many manufacturers (see FIG. 21 and FIG.220). While many manufacturers have the shape and position of theindividual components of the program are modified to show thedifference.

For example, as to the question of setting up a retaining part in aposition above the washing-basket in the bucket , there is a variety ofsame transformation, for example, it can be located in the upper portionof the washing-bucket, and it can also be provided on the lower surfaceof the lid, or a separate inner cover circle, not even flap, then thewater will naturally fall line after hitting the lid(this phenomenon iscalled the spray drops). Because the basket center of the cavity is aninstant low-pressure area, the water above will be sucked back into thebasket, which some people call the retaining part backwater retainingmember board. These water retaining parts are called backwater board,manger, water retaining reinforcement, block hydrosphere, even the waterretaining cover, which are almost all through the same means to achievethe same basic functions and the same effect. Although the changescaused by the location and the shape of the water retaining parts canmake the water into the basket in different position, the difference offalling points doesn't make any change in the effect of washingvegetables.

Another example, as to the problem of setting water institutions underthe washing basket, wash dishes are installed under the washing-basketin the original patent, and emphasis on that washing dishes and washingbaskets are synchronous and not move relatively. Under the revelation ofsuch a technical, then, when the washing-basket is made by plastic,technical personnel in the field of casting is easy to think that thewashing-basket and washing dish can be cast as a whole, simplifying thewash dish to water basket at the end of the function of the bulge. Inthe same way, the shape of the bump can have myriad similar variants,such as it can be made into cross, also can be made into X, also can bemade into rice word, or be made into swastika fonts, and so on, whichcan be called water board, dial article water, or the water bar, whichin short plays a role of raising water.

The above-mentioned Chinese patent No. 912 008 21.0 has been 20 yearsbefore the present.

Incidentally, now commercially available dynamic vegetable washers aremostly installed with ultrasonic generator ozone or ultravioletgenerating device or a plasma generating device, added with the staticvegetable washer functions, in order to remove the Group A impurities.

There is another structure of vegetable washer of existing technologythat the driving force above the basket, that the motor is mounted onthe lid of the washing-bucket. The structure of the washing-basket is along shaft with a rod in the bottom center, and the axis coordinateswith output axis of the motor under the lid of the bucket. The bottomsurface of the bucket has shaft seat raised, the shaft seat coordinateswith the recessed hole in the bottom surface of the washing basket, andas support for the washing-basket (see FIG. 23 and FIG. 26).

See FIG. 22, 23, 24, 25, 26, features of the two vegetable washers ofthe existing technology are:

1, No function of the division of Group B and Group C impurities and nodivision space.

2: Set shaft through 102 in the bottom center of the washing-bucket (seeFIG. 22 FIG. 25) or convex shaft seat 202, see FIG. 23 FIG. 26.

3: The outfall is set only around the bottom in the washing-bucket.

4: On the drainage method, there is no way to use the spinning suctionfrom the center of the vortex to discharge pollution.

5: The bucket shaft through the shaft seat 102 in the center of thebottom of the washing-basket or the raised shaft 202 as support for thewashing-basket (positing(positing a collar 104 on shaft 102 in order toincrease the bearing surface.)

6: The bottom of washing-bucket is flat or quasi plane.

7: The structure of the center in the basket's bottom is protruding fitconvex platform (FIG. 22 FIG. 25) or protruding rod long axis (FIG. 24FIG. 26)

8: The opening of the washing-basket is widely open.

Because of the vegetable washer of the existing technology with thesestructural features, after using it to wash vegetables, there are thefollowing three questions:

The first problem, Group C impurities are still mixed with vegetables,because: Group C impurities were thrown from the basket with the watercycle, rising to the top of the basket as the gap with the water bucket,but falling back to the vegetables in the basket with the water falling(if we call the water drops as spray, then spraying water down, whilethe impurities are spraying to the basket), so no matter how many timesbeen washed, finally Group C impurities are still mixed in thevegetables; you cannot split the problem of removal of Group Cimpurities.

The second problem, part of Group B impurities areis still mixed withvegetables, some accumulated in the bottom of the bucket around thecenter of the bucket shaft 102 and were not discharged. Because: duringdraining, the water flow no longer did upward motion along the gapbetween buckets and baskets with the reduction of water, and Group Bimpurities were so heavy that it sank to the bottom of the bucket, andgradually rotated to the bottom center of the bucket by the waterrolling, to gather around the center axis of the bucket. Precisely thecenter bottom of the bucket of the vegetable washer of the existingtechnology is a rotary axis, and the drain can only be set in around thebottom of the bucket, so these Group B impurities cannot be drained.Many consumers are not aware of this problem because the sleeve mountedto the shaft under the basket blocks the line of sight. Part of theGroup B impurities remain in the bottom of the bucket portion, partlymixed in vegetables removed by the user. Small parts are discharged fromthe drain opening by the bucket with the water falling—. That is to say,the Group B impurities and vegetables are still mixed in a bucket afterbeing washed one time. When put water into the bucket and start themachine again, the Group B impurities in the end of the bucketparticipate in the movement of water cycling up and down. (Such asconsumers reflected washing amaranth using the vegetable washer ofexisting technology, and then fry amaranth to eat, the upper and lowerteeth always grind to sand).

The third problem, there exists dead angle of cleaning, which is notconducive for the vegetables thoroughly cleaned. Because in the processof washing vegetables, no matter how many times we change the water orhow many times be washed in water, the vegetables in the cleaningprocess has been relatively concentrated near the side wall in thewashing basket, without a circumferential movement (be relative to thecircular movement of the basket), also without a centripetal movement,also without eccentric exercise again (except when the machine startedrunning first thrown into the washing-basket's vicinity). That is tosay, in the process of these vegetables receiving water's erosion, afixed positive side is maintained (because the water is a fixed path inthe loop), it will easily lead to dead angle of cleaning and is notconducive to thoroughly clean vegetables, which makes the degree ofwashing to clean compromised.

In other words, the existing commercially available vegetable washer hasjust finished of washing vegetables, but not finished the Y operation,and also cannot solve the problem of flipping fruits and vegetables in Xoperation, so strictly speaking, even X operation is not fullycompleted. Overall probably only completed 40% of the whole process.After washing vegetables with this vegetable washer, pesticide residuesmay be dissolved into the water with the water drained away due to theaction of ozone, and solve the degradation and removing of the Group Aimpurities, but Group B impurities such as weeds, insects, rottenleaves, stale leaves, hair and etc. are still mixed with vegetables inamong the basket, not being separated from vegetables; Group Bimpurities, such as sand, grit and mud, gather in the central portion ofthe washing-bucket and is partly mixed in vegetables, and would notdischarge with the water. When the second time putting water to washvegetables, came along with the irrigation of the vegetable washer androtation of the washing-basket, the sediment is connection withvegetables in the bucket, cannot be split, still need wash several timesartificially to complete the Y operation. That is to say, it does notreally achieve the liberation of the human and cannot entirely completethe whole process of washing vegetables by machines (X+Y operation).Strictly speaking, it cannot be called vegetables washed up, but onlysay that of half, or even less than half (due to the vegetables are notfully flipped, existing blind angle, which makes the degree of washingto clean compromised.)

These three problems are the reason that the vegetable washer can't bewidespread for a long time. Consumers who were not aware of theseproblems may buy this machine. The consumers who bought this kind ofmachine and found the three problems after using the machine would notrecommend their relatives and friends to buy the machine. (unless hisaim is to degrade the pesticide residue on the surface of thevegetables, willing to done Y operation manually. This does not makegreat difference to buy a static vegetable washer. Though Group Aimpurities are removed, the problem of removing Group B and Group Cimpurities didn't be solved thoroughly).

If you want to manually complete Y operation without solving the threeproblems, the dynamic vegetable washer exists meaningless. For example,in the cold winter, people have to manually wash vegetables once ortwice after washing them by the vegetable washer, but still cannot avoidthe hand being soaked into the icy water; another example is that afashionable lady, who paints her nails red, still cannot achieve washingvegetables without removing her makeup; another example, on someimportant occasion where people must eat raw vegetables in Western ,people still cannot avoid risks of infectious disease from hand washingvegetables and hand touching vegetables

If these three problems are solved, it must be a leap of “quality” fordynamic vegetable washer, because if these three problems are solved(together with ozone to remove Group A impurities), all the impuritiesin vegetables could be removed.

How to solve the three problems, which has been troubled the industry ofvegetable washer for not being solved in the past 20 years. Bothresearchers and manufacturers are trying to solve these three questionsof the existing vegetable washer, in order to complete the wholeprocess, the X+Y two operations, of washing vegetables completely by thevegetable washer, to tell consumers loudly that: “my vegetable washercan not only spin off impurities but also separate and divideimpurities, users can actually pour the vegetables into the pan to frydirectly after washing them by the machine”.

Researchers have been theoretically designed a variety of complexmethods in 20 years, trying to solve the three problems. For example: inorder to solve the problem of flipping vegetables, in some programs thevegetable washer is designed similar to tumbling-box vegetable washer,to boost the flipping of vegetables, see the technology program of drumvegetable washer in Chinese Patent No. 012 372 01.3. Another example: inorder to complete Y operation, which let vegetables and the threeimpurities in vegetables retained in a different space, some peoplesimulate mechanical hands to imitate human hands on existing vegetablewasher and use mechanical fingers to gripper vegetables from water andplaced them in another bowl. Although—the effect of these valuableexploration is not ideal, the explorer as a forerunner is undoubtedlyworthy of our later people's admiration.

The reason why these three problems are difficult to solve is that theexisting commercial vegetable washer obviously does not come out of theshadow of the laundry machine (for example: both the opening ofwashing-basket and washing-bucket are without shelter; both the centerof the bottom of washing-basket and washing-bucket exist axis acrossupward; and some other characteristics, such as the drainage openingsare around the bottom of the bucket), of course we cannot solve thesethree problems. Washing vegetables is unlike laundry: first, no matterhow dirty the clothes are, there are no much sediment, weed, staleleaves, and so on, but only the Group A impurities, such asperspiration, stains, dirt and etc., adhered to the surface of thegarment, so there is no need to fish out and divide Group B and Group Cimpurities, and the washing work is relatively much easier. Secondly,the water left after washing clothes can be directly discharged withoutclogging drains and drain valve, but washing vegetables is different,because a lot of water-insoluble Group B and Group C impurities are inthe vegetables, which would directly block up the nozzle of thedrain-pipe soon if discharged with the water into the drain-pipe. Calmlysay, even if the nozzle is not blocked, when Group C impurities go intothe outfall, it is very easy to make the rubber plug stuck in the rubberstopper at the drain valve, leading to leakage for the reason of therubber stopper closed out of the position.

After years of research, this patent solves all the three problems, andovercome the bias of this technology relying on spray vegetables andmakes a qualitative change of the washing cleanliness of vegetables, andachieves unexpected significant effect, which is completely removing allimpurities in vegetables. Moreover, implementing this patent tomanufacture the machine costs much lower, compared with many solutionsduring the 20 years.

SUMMARY OF THE INVENTION

To solve the above three problems of the existing vegetable washer,complete the entire process of washing vegetables by a machine, whichincludes the X operations and Y operations., the present inventiondiscloses the method of washing vegetables, which can split, separateand divide the impurities, and the machine which implement the method.This machine is also known as vegetable washer of drain contamination ofthe center attached by the impurities retractor, and the devices of thismachine in solving the three problems of the existing vegetable washerare used for simple structure, low cost, ingenious method, and theeffect is significant. It has a qualitative leap. Say this is notadvertising in the abstract but justified for the following reasons: Thereason why the effect is obvious is that there are four substancesincluding the three impurities and vegetables mixed in the basket at thebeginning, but these four substances are automatically split in fourdifferent spaces after washing, just like identified by the human eyes,like picked out by manpower picking. It can real achieve pouringvegetables in the basket directly into the pan to fry instead of pouringthe vegetables together with impurities into the pan to fry. The reasonof the ingenious method is that there is actually no need to add a lotof complicated machinery or a lot of cost to achieve such remarkableprogress-.

The washing method of washing vegetables, which can split, separate anddivide the impurities in the invention, comprises the following steps:put fruits and vegetables into the a water-permeable washing-basket inthe washing-bucket with a sealing cover, wherein the washing-basket isdriven by the motor to rotate such that the water is forced to be flungfrom inside of the washing-basket to the gap of the basket and bucket bythe centrifugal force, then rise to the top of the basket , and blockedand sucked down back into the basket; then, be flung to the gap of thebasket and bucket by the centrifugal force again, like this cyclingflow, each cycle of every stream of water goes through the gap of thevegetables in the basket, to form rapidly relative motion with thesurface of the fruit and vegetable, and form friction, to destroyimpurities attached to the surface of vegetables that is to be washed,and loose the clamping degree of vegetables to impurities. The presentinvention is characterized in that, this method has the following threetechnical features of A, B and C at the same time, or at least one ofthe following three technical characteristics A and B and C.

Feature A uses the method of “preventing the impurities flung out of thebasket with water to cycle and fall down back into the basket withwater” to clean the vegetables in the basket gradually. The subordinateconcept of this method includes the method of “adding dense sieve in theway of water's falling to retain impurities that was brought to themouth above the water and let the water continue to fall through thesieve”; Feature B uses a “vortex center draining ” _method to dischargethe sewage and impurities; The subordinate concept of this methodincludes the method of by: (1) opening a drainage outlet the center ofthe bottom of the washing-bucket and

rotating to wash the basket and draining off water at the same time toimplement draining contamination. So the opening of drain-pipe in thecenter of the drain in the bottom of the bucket is also the vortexcenter, where the water makes strong rotation to get the exclusion ofimpurities, especially the heavier Group B impurities such as sedimentwhich accumulates to the center of the bucket due to the rotationalmovement of water while the water level drops; The stated the opening ofthe draining off water and sewage in the center bottom of thewashing-basket is a center opening of the draining off water and sewagewhich can be closed and opened, and the stated washing-basket is abasket that without shaft to be connected to the center of the bottom ofthe bucket; in the washing-bucket there is a special carrying device tocarry washing-basket and special positioning device to limit thewashing-basket' s position and a special transmission mechanism willpass torque to the washing-basket, the “special” means “in addition tothe shaft connected with the center bottom of the bucket of thewashing-bucket or axle seat outside”.

Feature C is the method of flipping and turning the placement angle ofthe fruits and vegetables in the washing-basket, is making the vegetablein the washing basket periodically centripetal and centrifugal motion;Because of the above stated opening of central in the bucket draincontamination, uses the water flow centripetal motion in the process ofwater draining to drive fruits or vegetables to flip and scroll tobasket center, and next time when the washing-basket completes takingwater and the washing-basket begins to rotate or scroll, usingcentrifugal force to force fruits and vegetables to flip and scroll tothe edge of the basket, to achieve full rolling and flipping once more,so as to imitate effects of human flipping fruits and vegetables in thewater. Like this every time water is changed, each vegetable is placedto another angle and changed to another face as the face of the water.And this flip is done every time after we change water and is unlike theviolence when washing clothes in the washing, so it will not cause harmto fruits and vegetables. In a more than 20 minutes process of washingvegetables, you may need to change the water 4-5 times, there will be4-5 times the dish turned a switch, for a different display angle, andthere are 4-5 different positive sides, and the problem of the deadexists in washing vegetables in the existing technology is solved. Thestate three features of methods, feature A, feature B and feature C canexist in one vegetable washer at the same time, or there are only one ortwo of the three exist in one vegetable washer.

Of course, only when three features are equipped the vegetables can becleaned thoroughly to the highest degree. Moreover, feature A is theprerequisite technical of feature B. If there is no feature A butfeature B, then because the problem that the Group C impurities are notsplit and collected is not resolved, the Group C impurities will betaken into sewage pipes clogged sewage by the vortex, that is to say,the setting of filter in the basket port is the prerequisite technicalof central sewage. If there is no feature B but feature A, then becausethe problem that the Group B impurities are not split and collected isnot resolved, the invention's purpose, clean and remove impuritiescompletely, cannot be completed, too. That is to say, In other words, Aand B mutually cooperate to work.

As we all know, in the vegetable washer, the cross-section of bucketchamber of the washing-bucket and the cross-section of thewashing-basket is a pair of concentric circles, so shaft of thewashing-basket naturally goes through the center of the concentriccircles. So, in the center of the bottom of the bucket of the vegetablewasher in the existing technology sets up rotation axis penetratedupward (see FIGS. 22 and 25) or in the center bottom of the bucketlocated pedestal (see FIGS. 23 and 26) is also a matter of course, andnothing wrong; this set is a necessarily association of technician inthis technical field. And the innovative thinking and creative work ofthe present invention lies in abandoning the often irrational andconventional program. Open an outlet in the center bottom of bucketfilled with water, and the sewage effect has been improved essentially.If coupled with the bottom of the bucket as funnel-shaped, Drainthoroughly.

As we all know, all the vegetable washers in the existing technologystress washing vegetables by spraying, called “spray technology”, whichemphasizes water returns from above and fells off in the washing-basket,and felling off in the washing-basket mainly plays the role of washingvegetables, but in fact, this is a technology bias (see the attachedarguments). This technology bias guides people try to open the mouth ofthe basket, and cannot have the cover so as not to slow down the fallingspeed of the water flow and affect the placement of water, while thepresent invention is on the contrary, and overcomes this technicalprejudice, located in export processing basket dense filter whichaccumulated a great deal of Group C impurities and some Group Bimpurities, objectively slowing the flow rate and affecting theplacement of water which is random and irregular (affected to thedistribution of impurities detained). But the washing effect improvedsignificantly.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeatures: strengthen impurities closer to the center by making thebottom of the bucket into the low-center high-around and funnel-shapedto enhance the impurities to gather to the center, thereby strengtheningthe vortex flow on discharge of impurities: funnel describe rotatingblade chamber can be set aside in order to strengthen the effect ofwater, can serve as the axis of rotation of the blade extending downwardfrom the axis of rotation of the washing-basket. The preferredembodiment of the bottom of the washing-basket is flat or hopper.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature: By making the bottom of the bucket into the low-centerhigh-around and funnel-shaped to enhance the impurities to gather to thecenter, and this device is called the filter under the basket; of whichthe skeleton can be used as a supporting member of the basket, or notthe support member. The density degree of meshes of the filter is to beable to prevent large leaves passing and without hampering the sedimentspassing and discharge, within this range the meshes' size is changeable,preferably between aperture 2 mm to 5 mm.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature: Motor drives the washing-basket to rotate, power of the motormay be transmitted to the basket from any position of the basket, andcan be passed to the basket from above or below or side to the basket.When passing from the top to the basket, one of the passing method isselectively using the filter's skeleton in the basket's port as atransmission member, or may not choose to use the filter's skeleton inthe basket's port as a transmission member.

The machine of the method of the present invention is a kind ofvegetable washer that can split and separate the impurities invegetables, including the basket in the washing-bucket with a sealingcover, in the chassis there is equipped with motor and the electroniccontrol device that drive the washing-basket to rotate, it has features:this machine has following both A and B two technical features at thesame time, or has any one of the following two technical features A andB. Feature A is that set the filter device near the port of thewashing-basket, for the convenience of description, it can be calledbasket's port filter, or impurities blocker, or contaminant retentiondevice. Basket's port filter is coated with dense filter screen ,screen,the aperture of the meshes as small as possible under the premise ofwater flowing through, preferably in the range between 0.1 mm to 1 mm.The subordinate concept of the stated “Settings” includes fixing thehinge, snap-fixing, fixing screwing, bolts, friction fixed, fixation pinplug, etc. The stated “near the port of the basket” means the range ofin the washing-bucket and the height below the height of thewashing-bucket's cover and above the end of the washing-basket,including the location of the port of the washing-basket or the innerwall of the washing-bucket or the inner surface of the cover. The effectis to make the water flow back into the washing-basket and continue loopand run, and stop the impurities flowing down to the washing-basket andcontinue looping and running, left the Group C impurities (and part of Bimpurities with the water rising) retained in the filter screen of thebasket's port. The preferred program is that the filter mesh covers theabove opening of the washing-basket. Any other equivalent transformationand the inevitable association revelation in this technique violates“infringement by equivalents” in “doctrine of equivalents”. Feature B isthat open an outfall of draining off water and pollution in the centeror quasi-center of the bottom of the bucket, this outfall connected tothe outside world by drain pipe, and the outfall may be coupled to thefilter mesh when necessary, and the effect is that in the process ofrotating to wash the basket and draining off water, the rotational speedof the center of the outfall is much faster than the surrounding, andcan make a powerful vortex suction to suck and discharge a largerproportion of deposits of Group B impurities (sand and grit) in thebottom of the bucket, while making the vegetables which are relativelyconcentrated and stayed near the side wall of the washing-basketattracted to the center of the washing-basket with draining off water,to achieve rolling and flipping the vegetables, and prepare for the nexttime the basket begins to turn after the basket finishing inlet waterand the centrifugal force takes fruits and vegetables to the edge of thebasket, to achieve full rolling and flipping once more, and imitatehuman effects of fruits and vegetables flipping in the water. Like thisevery time water is changed, each vegetable is placed to another angleand changed to another face as the face of the water, and this flip isdone every time after we change water and is unlike the violence whenwashing clothes in the washing, any other equivalent transformation andthe inevitable association revelation in this technique violates“infringement by equivalents” in “doctrine of equivalents” . The statedthe opening of the draining off water and sewage in the center of thebottom of the washing-bucket is a center opening which can be closed andopened, and the stated washing-basket is a basket that without shaft tobe connected to the center of the bottom of the bucket; in thewashing-bucket there is a special carrying device to carrywashing-basket and special positioning device to limit thewashing-basket's position and a special transmission mechanism will passtorque to the washing-basket, the “special” means “without shaft orshaft-seat connected with the center of bottom of the bucket”.

The state two features of structures can exist in one vegetable washerat the same time, or there are just one exists in one vegetable washer.Of course, only when two features are equipped the vegetables can becleaned to the most thorough.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature: the bottom of the bucket is high-low center around thefunnel-shaped bottom to strengthen impurities' discharge; funneldescribe

rotating blade chamber can be set aside in order to strengthen theeffect of water, can serve as the axis of rotation of the bladeextending downward from the axis of rotation of the washing-basket. Inaddition, the washing-bucket bottom of the bucket is provided a round ofannular steps.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature: set filter apparatus below the basket and above the drain pipe,the meshes' aperture of the filter are much sparse, as the standard ofpreventing the adoption of Group C impurities but passing through GroupB impurities, within this standard the meshes' size is changeable,preferably between 2 mm to 5 mm. Filter frame under the basket can beused as a support member of the basket, and can be not the supportmember of the washing-basket.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature: Motor drives the washing-basket to rotate, power of the motormay be transmitted to the basket from any position of the basket, andcan be passed to the basket from above or below or next to the basket.When passing from the top to the basket, the method of passing canselectively use the filter's skeleton in the basket's port as atransmission member, or may not choose to use the filter's skeleton inthe basket's port as a transmission member; When the rotation axis ofthe washing-basket or that of the tray of the washing-basket, and powerinput shaft that connected to the axis are a pair of crossed, which areconnected by conventional binding mechanism well known in mechanicalfield, the subordinate of the stated well known binding mechanism wellknown includes: worm, universal joint, cross coupling, bevel gear, andso on.

The method of washing vegetables that can split and separate impuritiesin this invention, can also be added with the following technicalfeature:

The cone surface surrounded by the ring skeletonand spoke fixing drape filter 8-6, of course, the size of the projectedarea of the filter and the size of the cross-sectional area of thewashing-bucket are also quite cavity; Filter 8 is fixed in the bottom ofthe washing-bucket at the mouth of the funnel under the basket by thefixing bolts 8-3. In this case the filter under the basket is also asupport member, telescoped together by the tray assembly 7 to supportthe washing-basket. The stated tube bearing 8-1 may be instead by thetubular sleeve and the plane bearing fixed in the pipe opening.

The head-neck shaped bolt 7-3 on the tray assembly 7 holes up into thepin holes in the bottom of the washing-basket, and the pin holes areround holes in the middle and strip holes on both sides of the arc,space of the round holes work with the head-neck shaped bolt, so thatthe washing-basket can be easily separated from the tray removed orre-placed in the tray, and transmit the rotation torque through theplug; The central tray 7-2 of the tray assembly goes through the centralbearing 8-1 of filter 8 under the basket, put down into thefunnel-shaped cavity of the underpart of washing-bucket cavity, and thecentral axis 7-2 and the central bearing 8-1 cooperate interference. Theend of the central axis 7-2 is fixed with flaky dial water slurry 7-1.The stated tray is permeable hollow.

The horizontal projection of the filter 2 is circular ,and the size ofthe projected area is equal to that of the washing-basket's inlet; thefilter in the inlet has an inverted umbrella-shaped frame, including: avertical straight tubular sleeve 2-1, the ring skeleton 2-4 aroundperiphery, the spoke 2-5 is between the sleeve and skeleton, and thespokes can have one or multilayer (in order to increase strength, onepoint in the spoke and one point in the sleeve can be re-welded steelbars with supporting, not shown in this case to be straightforward). Thecone surface surrounded by the ring skeleton and spoke fixing drapefilter 2-6, of course, the size of the projected area of the filter andthe size of the cross-sectional area of the washing-bucket are alsoquite; There is bolt 2-3 underneath the outer periphery of the ringskeleton. When working, filter 2 in the basket's port covers on themouth of washing-basket 3, around the basket's mouth are several jacks3-2, which cooperates with plug 2-3. In this case the filter in thebasket's mouth is also a power transmission component, receive torquepower from the top shaft 1-4 through the sleeve 2-1, and pin inserted tothe jacks 3-2 around the mouth of the basket through the plug 2-3 topass the torque force to the basket.

Leave proper clearance 4 between the inner wall of the washing basket 3and the washing-bucket 5, the up cover 1 of the washing-bucket 5 ishinged with the body through the hinge axis 1-5, to achieve the lid'sopening and closing through the rotation of the hinge axis, to achievethat the bucket closes the cover by spring deduction 1-6, around the lidsets a waterproof sealing tape. Above the lid sets a gearbox for gearmotor assembly 1-3 to hold the gear motor, output shaft 1-4 of the gearmotor goes through the cover of the underside of the lid and the headinserts into the central filter sleeve 2-1 of basket's opening, shaftand sleeve are connected with spline lenient 2-2. Shaft 1-4 drive sleeve2-1 to rotate so as to drive the filter at the mouth of the basket.

In the cavity of the body shell 6, the underpart cavity is set withwater inlet 9 and the inlet valve assembly 9-1, and the inletcommunicates with the washing-bucket, so that water can automaticallydraw into the washing-bucket 5 under the control of the controller.There is water level controller to monitor water level in the cavity(for simplicity, not shown in the picture).

In the cavity of the body shell 6, the underpart cavity is set withdrain 10 and the drain valve assembly 10-1, and the drain is connectedwith central bottom of the washing-bucket, or quasi-center. In this casethe lower part of the washing-bucket is funnel-shaped, and the center isthe lowest, so it can form effects of -powerful vortex sewage.

The upper part of the front of fuselage has an operation panel 23, inwhich there is corresponding controller 22. By operating the controlpanel buttons, to achieve the operation of the controller. Thecontroller can automatically control water inlet and drainage and thecleaning procedures.

See FIG. 2 and FIG. 3, in order to be more conducive for understandingthe embodiment, FIG. 2 provides the assembly diagrammatic drawing of thefirst embodiment of the present invention, FIG. 3 is the label of allparts in FIG. 2 (for simplicity, parts of this specification schematicsectional drawing show not symbols).

FIG. 4 is the schematic of the washing-bucket and chassis of the firstembodiment of the present invention, that is the schematic that thefilter in the basket's opening and the washing-basket and filter underthe basket and tray assembly have not been installed, and in the figurethe snap hook 1-6 of the lid and the bucket body does not catch live, sothe lid bounce a certain angle due to the action of the spring hingeaxis 1-5.

See FIG. 5 and FIG. 6, in order to be more conducive for understandingthe embodiment, FIG. 5 provides the schematic drawing of thecombinations of the filter under the basket and the multifunctional trayof the first embodiment of the present invention. FIG. 6 is a schematicdrawing that FIG. 5 is installed in FIG. 4 (for simplicity, the filtermesh under the basket are not shown).

See FIG. 7 and FIG. 8, FIG. 7 is a cross-sectional schematic view of thefilter in the basket's inlet of the first embodiment of the presentinvention, and in the drawing the aperture of the filter screen is notpainted in proportion, but as a hint, and the filter screen of thebasket's inlet in the other figures of the first embodiment are notshown in addition to FIG. 7, FIG. 8 is a stereoscopic schematic view ofthe filter in the basket's inlet of the first embodiment of the presentinvention.

When working, put fruits and vegetables into the basket, and put latch2-3 of the filter of the basket inlet insert into the jack 3-2 ofwashing-basket inlet to make filter 2 of basket inlet cover the basketinlet. Then cover with the lid, at the same time, slow down the motor'soutput shaft 1-4 can be easily inserted the sleeve 2-1. Then open theinlet valve, under the control of the water level controller draw waterto a predetermined level and close the backward valve. Then the motorstarts, at the same time the output shaft 1-4 of the gear motor rotatesdrive sleeve 2-1 to rotate through the loose big gap splines 2-2 so asto drive the filter of the basket inlet 2 to rotate. Because latch 2-3of the filter of the basket inlet insert down to the jack 3-2 ofwashing-basket inlet to drive the whole washing-basket to rotate. Andbecause the head-neck shaped bolt 7-3 on the tray assembly 7 holes upinto the pin hole associated with it in the bottom of the washing-basketso that the washing-basket drive the tray to rotate. Because the trayhas the downward extending shaft 7-2, the shaft can be synchronized withthe rotation of the housing in the circumferential direction, so thatthe two pieces of water repellent sheet that are fixed to the shaft'send rotate synchronous and repellent the water; and because the shaft7-2 and the central tube bearing 8-1 of the filter under the basket areinterference fit, the shaft is fixed with the bearing 81 in the axialdirection, while the filter under the basket is fixed by the screw 8-3to the bucket body, therefore in the axial direction, the tray is fixedto the bucket body, and also play a supporting role to thewashing-basket.

With the rapid rotation of the washing-basket, fruits and vegetables inthe basket as well as the water do the centrifugal movement, and fruitsand vegetables move to the basket's side and was blocked by the basket'swalls and stay near the side wall, while the water flow is flung by thecentrifugal forces from the washing-basket to the gap 4 of basket andbucket, then rise to the top of the basket, then water is drawn out withGroup B impurities and Group C impurities, and part of Group Bimpurities sink to the end of the bucket, and the rest Group Bimpurities and Group C impurities that are thrown together with therising water flow, rises to the above of the basket, and are hampered bythe top lid or the erected retaining ring above the bucket and down tothe center of the filter mesh in the basket's mouth, and theseimpurities cannot pass through the dense mesh and retained in the filtermesh in the basket's mouth, to complete Y operation. While the waterflow passes through the filter strainer of the basket ports and continueto fall into the basket, and then, be flung to the gap of washing-basketand washing-bucket by the centrifugal force again, like this cyclingflow, each cycle of every stream of water goes through the gap of thevegetables in washing-basket, to form rapidly relative motion with thesurface of the fruit and vegetable, and form friction, with the surfaceof fruits and vegetables, produce friction to impurities and vegetablespin off to complete the X operation. The most crucial point is thateach cycle of every water flow takes Group B impurities and Group Cimpurities mixed up with vegetables out of the washing-basket, and intothe filter of basket's mouth. Then, these Group B impurities and Group Cimpurities stay in the filter of basket's mouth. That is to say, theseimpurities leave the basket and cannot comeback into the basket, neverreturn, they will be no return to the vegetables if leave thevegetables. In this example set the vegetable washer's basket 200revolutions per minute, a program of rotating with 20 minutes, about4000 rpm, even if every turn brings a little bit of impurities (Note: noreturn impurities, there will not fall back into the basket ifimpurities come up), a little bit in 4000, it is not possible withoutcleaning up the impurities. Impurities in washing-basket is reducingevery second, this second are less than last second, the next second areless than this second, and all gradually lien to the filter of thebasket's mouth. The water flow not only plays the role of water erosion,but also plays the role of scouring, while by the vegetable washer ofexisting technology, water only plays the role of scouring.

While in the vegetable washer of existing technology, because there isno filter at the mouth of the washing-basket, impurities are thrown fromthe basket's side, up to the basket's opening, and spray down to thebasket from the basket's opening, no matter how many times water cycleup and down and inside and outside, these Group C impurities and part ofGroup B impurities also cycle so many times along with the watercycling. Water in washing-bucket is discharged, Group C impurities andpart of Group B impurities are still mixed in the vegetables, especiallyworse to the situation of leafy. Therefore, in video advertising ofvegetable washer in the existing technology, we have never met thatpeople take these vegetables such as leek garden chrysanthemum amaranthwatercress with much more impurities for examples to wash, and often seethem take apples peach lettuce and other ingredients that are easy toclean.

The filter of the basket inlet has the function of blocking impuritiesto backflow and storing up impurities, so it is also known as impuritiesblocker, or contaminant retention device.

In this embodiment, the control panel 23 is slated to have many timeplans and speed options available to suit the needs of different user'spreferences and different fruits'and vegetables'needs. Scheme in thiscase is set for a total of 24 minutes through the wash process, fourtimes running. Each time the water inflow takes one minute and thenrotating washing takes 3 minutes and then begin to open the drain valvewhile rotating water drain for about one minute to complete the washingone time. The whole process carries on a total of four times in thewater—wash—drainage. In four minutes of the rotating washing it cancross clockwise rotation and counterclockwise rotation.

Now discuss the feature of the sixth minute work in this case: use themethod of cleaning of the vortex center to remove the sewage water andimpurities. The controller opens the drain valve according to the setprocedures, then washing-basket continues to rotate in a clockwisedirection, the flow continues to rotate in a clockwise direction, andthe water forms vortex in the center of the bucket spinning flowing outof the washing-basket and is discharged out of the washing-bucket by thedrain. Since the drain 10's opening in the bottom center of thewashing-bucket 5, then the rotational speed of the water near the mouthof the drain is quite quick, and quickly roll Group B impurities whichare deposited in the funnel-shaped bottom of the bucket into the drain,and water continue to rotate after going into the drain due to inertiawill, rotating and going forward, which acts like a bullet having arifle movement inside the barrel, can remove Group C impurities morethoroughly to the outside world, and eliminate sand accumulated nearbyrubber plug in the drain valve to avoid leakage.

Also, before the drain valve open, there are parts of heavy Group Bimpurities, when rotating to the drain's opening at the center bottom ofthe bucket, having dropped to the drain to wait for the discharge, thatis to say, the drain provides indwelling space for Group B impuritiesand becomes indwelling devices of Group B impurities. In this way, whenthe washing-basket is rotating and working, Group B impurities inwashing-basket is reducing every second, this second are less than lastsecond, the next second are less than this second. While the vegetablewasher in

existing technology, because there is no opening in the bottom center ofthe bucket, most of Group B impurities (except parts with water risingand cycling) accumulate center around axis 102 in the bottom.

The vegetable washer of existing technology, since in the central bottomof the bucket sets the rotation axis, the drain's opening can only beset at the edge of the bottom of the washing-bucket, and it fails toachieve this effect, see FIG. 22 and FIG. 23. There exist four defectsin this bucket-bottom structure of the existing technology: First,because of the water's rotation large number of Group B impuritiesaccumulate in the central area of the bucket's bottom (near the axis ofFIG. 22 or near the shaft seat of FIG. 23), these impurities cannot bedischarged from the drain provided in the drain edge of the bucket'sbottom. Second, the sand particles longterm accumulating in the vicinityof the axis are likely to be involved in the gap of shaft and waterproofcup, causes cup scratches and scratches causes sealing leakage. Third,the hydrodynamic characteristics of the sewage flowing to the centeroutlet while rotating cannot be used to take away the impurities,particularly Group B impurities. Fourth, water flow cannot be dischargedby rifled type moving after going into the drain pipe, to theaccumulation of sand flowing through the drain valve when in thevicinity of the rubber plug in the drain valve, which easily lead to arubber stopper loose relationship, leading to water leakage.

As we all know, the cross-section of the washing-bucket's chamber of thevegetable washer and that of the washing-basket are a pair of concentriccircles, so the shaft of the washing-basket of course goes through thecenter of this pair of concentric circles. Therefore in the centralbottom of the vegetable washer of existing technology there sets therotating shaft go through upward (see FIG. 22) or set shaft seat at thecenter bottom of the bucket (see FIG. 23) is also a matter of course,nothing wrong; this setting is an inevitable association of a staff inthis technology. And the innovative thinking and creative work of thepresent invention lies in the irrational setup program that abandons theconventional. Open the outlet in the bottom center of the bucket filledwith water, and the sewage effect has been improved essentially. Coupledwith the bottom of the bucket made as funnel-shaped, sewage is verythorough.

Now discuss the operating characteristics of sixth minute to eighthminute in this case: the fruits and vegetables make periodic heartmovement and centrifugal movement, in order to achieve the placementangle of flipping and flapping fruits and vegetables in the basket. Thesixth minute, the controller opens the drain valve according to the setprocedures, then washing-basket continues to rotate in a clockwisedirection, and the water flow continues to rotate in a clockwisedirection, due to the opening of drain 10 opens in the center bottom ofthe washing-bucket 5, the water rotates to the center from all around,and form vortex in the center of the bucket spinning out of thewashing-bucket and discharge outside by the drain. The water flow alsodrives fruits and vegetables to move towards the center of the basket(including scrolling and flipping). Until the water is drained, closethe drain valve. Fruits and vegetables changes from the “relativelyconcentrating remain near side walls in the washing-basket” to“relatively concentrating remain near the center in the washing-basket.”The seventh minute, according to set procedures the inlet valve opensthe second time, penetrating water under the control of the water levelcontroller to a predetermined level and then backward valve is closed.Next the eighth minute, motor starts, then output shaft 1-4 of gearmotor rotates and goes through splines 2-2 of a large loose gap drivingsleeve 2-1 to rotate so as to drive the filter 2 of the basket's inletto rotate. Because latch 2-3 of the filter of the basket inlet insertdown to the jack 3-2 of washing-basket inlet to drive the wholewashing-basket to rotate. Thereby drive water repellent plate 7-1rotates together to repellent, thereby drive the whole bucket of waterin the washing-bucket to rotate together. With the rapid rotation of thewashing-basket, fruits and vegetables in the basket as well as the waterdo the centrifugal movement, and fruits and vegetables move to thebasket's side and was blocked by the basket's walls and stay near theside wall, and back to the position before the original drainage. Thesame of the process of centrifugal movement and the process of theconcentric movement is the process of fruits and vegetables sufficientlyrolling and turning, to achieve the effect of replacing manual turningfruits and vegetables in the water .Like this every time water ischanged, each vegetable is placed to another angle and changed toanother face as the face of the water. And this flip is done every timeafter we change water, and is unlike the violence when washing clothesin the washing, so it will not cause harm to fruits and vegetables.

The stated output shaft 1-4 and sleeve 2-1 use a large loose gap key,for example, only four or three teeth, etc. are for convenience when youput the lid the shaft 1-4 can be easily inserted into sleeve 2-1, aslong as achieving this purpose and can play a driving role, it can be OKin any other conventional mechanical solutions. For example geartransmission cross shaft surface can be all right in the field ofmechanical.

Whether the stated washing process to be introduced into the ozone ornot , there are two options for users to choose on the control panel 23.If desired, may according to the program automatically inlet ozone intothe washing-bucket 5 by the ozone generator 11 within a predeterminedtime. Discharge excess ozone residue through the filter chamber 1-1.

Left the proper clearance 4 between the inner wall of the washing-basketand washing-bucket as water flow's rising channel. Now that it is thechannel, the diameter is the same as a water pipe, and the width of thechannel can only be determined based on the desired flow rate and flowspeed which are affected by the size of the bucket and speed of thewashing-basket's rotation. Therefore, it cannot have a uniform value,such as a same number, is not the best choice of two washing-buckets ofa small diameter and a big diameter. But by the logic of the relevantamounts described in this paragraph, we can calculate the value for theoptimum gap to specific examples step by step through the experimental.

FIG. 9 is the second embodiment of the present invention. The differencebetween this embodiment and the embodiment 1 is: the filter 8 under thebasket is a disc-shaped planar filter, fixed in the center of the bottomof the bucket; the washing-bucket's bottom is flat; around thewashing-basket is mounted three or more wheels 12-1, playing the role ofa radial positioning; when the washing-basket rotating, use the rollingfriction of the wheel with the inner wall of the washing-bucket to avoidthe sliding friction and collision of the basket with the inner wall ofthe bucket, while allowing the washing-basket's taking and placing, aspherical square wheel is used in the figure; bottom surface of thewashing-basket is mounted a pulley 12-2, plays the role of carrying thewashing-basket, together with the lid and the filter of the basket portdefine the axial position of the washing-basket, spherical casters areused in the figure; a downward projecting elongate repellent article 3-1in the end of the basket , the allocation of water can have multiplepieces, forming a cross-shaped cross or X-type or can also be made intorice-shaped swastikashaped (refer to seeing from bottom angle) and soon.

If allowing the instructions attached figures using photographs, I canprovide the material photographs of FIG. 22, FIG. 23, FIG. 24 and FIG.26.

According to the components of the above examples make simplerecombination to produce new implementations, all of which belong to thescope of patent protection of the same transformation. And because manycommon parts and well known transmission mechanism in the field ofmechanical can be replaced with each other to achieve the same purpose,any of the embodiment converted out are within the scope of patentprotection of the same transformation.

Now demonstrate that the vegetable washer depends mainly on the waterflow spraying vegetables is a technology bias. As we all know, all thevegetable washers in the existing technology stress washing vegetablesby spraying, called “spray technology”, which emphasizes water returnsfrom above and fells off in the washing-basket, and felling off in thewashing-basket plays important role in washing vegetables, This can beseen from television advertising of the vegetable washer of the variousmanufacturers, sales page of selling vegetable washer online. But infact, this is a technology bias. This technology bias guides people tryto open the mouth of the basket, and cannot have the cover so as not toslow down the falling speed of the water flow and affect the placementof water, while the present invention is on the contrary, and filter islocated in the basket's inlet, and in the dense filter accumulated agreat deal of Group C impurities and some Group B impurities,objectively slowing down the flow rate and affecting the placement ofwater which is random and irregular. But the washing effect improvedsignificantly. That proves that when water drops the so-called “spray”does not play a key role in washing vegetables, that is, phenomenon ofwater spraying does exist, but just a kind of water cycling phenomenonof dynamic vegetable washer.

Experiments show that regardless of the placement of the water in thecenter of the basket or around the basket that is the top of thevegetables (note: vegetables stay surrounding the basket), the washingeffect is due to the friction of the gap when water goes throughvegetables, rather than the sprinkling of water falling. Because fruitsand vegetables are staying within the containment of water from thebeginning to the end, and the falling water cannot catch in fruits andvegetables no matter where the whereabouts is. The swimmer can realizethis principle most: when a man is swimming in the pool it suddenlyrains heavily, his head and shoulders exposed on the surface can feelthe rain, but below the surface portions such as loins and legs do notfeel the rain, when his body was submerged, then no matter how heavyrain is his body cannot got caught.

Since water's placement has no effect on cleanliness of washingvegetables, the shape of the backwater plate (or called rib flapretaining bar curb retaining piece, etc.) is not important, and can bestand sheet of various shapes.

1. A method for cleaning fruit and vegetable food materials ischaracterized in that the fruit and vegetable food materials are putinto a washing basket, the washing basket is arranged in awashing-bucket, the bottom center of the washing-bucket is provided witha drainage outlet, the drainage outlet can be opened and closed, thewashing-bucket or the cover of the washing-bucket is connected with anmachine box, and an electric machine driving the rotation of the washingbasket and a control unit are arranged in the machine box. Runningelectronic control equipment; injecting washing water into thewashing-bucket to immerse the fruits and vegetables to be washed and thewashing basket in water; starting the electronic control equipment tomake the motor drive the washing basket to rotate, and the rotation ofthe washing basket agitates the water in the washing-bucket to make thewater in the washing-bucket rotate upward motion. The movement path isthat the centrifugal force is thrown from the inside of the washingbasket to the gap between the basket and the -bucket—then rises to thetop of the basket once again—the water baffle is directed to thecenter—then falls back into the basket—and then is thrown into the gapbetween the -buckets by centrifugal force, so that the reciprocatingflow lasts for a certain period of time, referred to as “the cycliccleaning movement in the -bucket”. Each cycle of water flow passesthrough the gap between the vegetables in the basket, thus forming arapid relative movement with the surface of fruits and vegetables,generating friction, to destroy the attachment of impurities on thesurface of the washed objects and loose vegetables. During the processof “cyclic cleaning movement in the -bucket”, the drainage outlet at thebottom center of the -bucket is closed to prevent the water from flowingout of the -bucket cavity of the washing-bucket; after the end of the“cyclic cleaning movement in the -bucket”, the drainage outlet at thebottom center of the -bucket is opened, and the sewage is dischargedthrough the drainage outlet. The dirt outlet discharges out of the-bucket cavity; the washing basket assembly is composed of the washingbasket body and the special supporting device, the special positioningdevice and the special transmission device, which coordinate to completethe agitation of water and form a rotating upward flow. The specialsupporting device plays a supporting role on the washing basket. Thespecial positioning device limits the position of the washing basket andthe special transmission machine. The mechanism transfers the torque ofthe motor in the chassis to the washing basket. The “special” refers to“not occupying the bottom center of the washing-bucket”, or “neitheroccupying the bottom center of the washing-bucket nor occupying thecenter of the bottom of the washing basket”, without hindering theopening of a drainage outlet in the bottom center of the washing-bucket;in the process of “cyclic cleaning in the -bucket”, the fruits andvegetables in the basket moves centrifugally to the edge of the basketand stays at the edge of the basket;. Said water baffle is a waterbaffle in the prior art or is used as a water baffle by the cover of thewashing-bucket.
